Cut butter into pieces and place in the bowl of a stand mixer along with the flour, honey, and salt. Place in freezer for 30 minutes.
Add half the amount of eggs, the yeast, and melted 24 g Prova Gourmet Fusion Rum Flavored Cocoa Butter. Knead on the second speed setting, gradually adding the remaining eggs, until the dough pulls away from the edges of the bowl. Dough should be 75°F once kneaded.
Transfer dough to a piping bag and pipe into silicone ball-shaped molds and leave it to rise for 1 hour.
Bake, with the mold placed between 2 baking sheets, at 320°F for 20 minutes. Remove babas from molds and bake for an additional 5 minutes to brown.
